Alumilite - RC-3 AlumiRes Casting Resin

RC-3 AlumiRes Casting Resin

Cast detailed reproductions that cure hard in 30 minutes and machine clean

A 1:1 mix ratio eliminates complicated measuring, while the two-minute work time gives you enough window to pour multiple molds before the resin kicks. Demold in thirty minutes from a 100-gram mass, then move directly to finishing work.

This polyurethane resin captures intricate surface detail with the kind of clarity that makes mold preparation worthwhile. Cured pieces machine cleanly, drill, tap, and sand without chipping or cracking. The hard, durable plastic accepts paint and finishes readily, whether you're producing prototype parts or decorative castings. Virtually odorless formula means you can work in standard studio ventilation rather than requiring specialized extraction.

Compatible with silicone rubber, Alumilite Flex Molds, latex, plaster, and sealed non-porous surfaces, RC-3 handles diverse mold materials without adhesion issues. The kit includes 16-ounce bottles of parts A and B, two mixing sticks, and three graduated cups, everything needed to start casting immediately. For sculptors, model makers, and prop fabricators managing volume production, this resin keeps projects moving without inflating material costs.
